I would like to see "Ground Distance Template Cursors" built into ArcMap.
These would be rings or boxes that move along with the standard pointer regardless of the setting, (They would exist whether you were collecting a feature, using the hand tool, drawing a box, etc.)
The purpose of these would be to help visualize distances without using the measure tool. User could set multiple rings, specify color, thickness and transparency. User would also specify the radius distance (feet, meters, inches, etc) and ArcMap would handle whatever conversion was necesscary based on current map. Also could specify an area... for example a two acre cursor.
These rings would scale dynamically as the map is zoomed in or out to always show the selected ground distance.
I think this would be very useful to visualize distances.... sometimes project criteria calls for us to digitize features from imagery.... may call for lakes > 1 acre and Rivers wider than 100'. If we had these specialized cursors, then without using the measure tool, a user could tell at a glance if a feature met those qualifications.
Please consider this for future update.
